Control of these two straights would give them access to the Mediterranean Sea.

If it is to the Mediterranean Sea it would be The Bosporus and The Dardanelles Strait's.

It gave Russia a port that was accessible so supplies could be sent to them. As they were running low on supplies but had many men.
Geographic boundaries between the continents of Europe and Asia are the Ural Mountains, the Caucasus Mountains, and the Dardenelles strait between in Turkey that leads between the Black Sea and the Aegean Sea.
There is no such city. Russia does not border the Mediterranean. At best, Russia would have to use one of its Black Sea ports and then have the ship travel through the Bosporus, into the Sea of Marmara, into the Dardanelles Straits, and through the Aegean Sea to get to the Mediterranean Sea.
The Dardanelles Straits connect the Black and Mediterranean seas. During World War I, it was controlled by the Ottoman Empire, one of the Central Powers. Unfortunately, it was the only way to get supplies to Russia. Britain needed the straits to help its ally.
The purpose of the Gallipoli Campaign was to capture the Dardanelles Straits that were held by the Ottoman Empire. The straits would allow the Allies access to the Black Sea and thus they could get to Russia using a route other than the German-patrolled North and Baltic Seas.
The Dardanelles were crucial during World War I as they provided a strategic maritime route connecting the Aegean Sea to the Sea of Marmara, facilitating access to the Ottoman Empire. Control of this passage was vital for the Allies to supply Russia and to potentially open a new front against the Central Powers. The ill-fated Gallipoli Campaign aimed to secure the Dardanelles but resulted in significant Allied losses and highlighted the challenges of amphibious warfare. Ultimately, the campaign's failure reinforced Ottoman resistance and affected the overall dynamics of the war.
Russia was old fashioned and weak- it collapsed because it was unsuitable.

The major goal of the campaign was to capture the Dardanelles Straits from the Ottomans and open a line of supply to Russia through the Black Sea.
